GHARCQAlL-KILN.

To all whom it may concern Be it known that l, ALFRED RQWEBEL- any, asubject of, the King of Great Britain, residing at Spittlegate lronJVorks, Grantham, liinco'lnshire, England, have invented new and usefulImprovements in Charcoal-Kilns, of which the following is aspecification.

My invention relates to kilns for charcoal burning.

Charcoal kilns have already been proposed which comprise a body having aseries of inspection and air holes distributed over it in a staggeredformation, and provided with a charging opening at the top and a conicalbottom fitted with a sliding door serving a double function, namely,that of controlling the discharge of the contents of kiln, andof theinlet of air into the bottom of the latter. l'n suchkilns it is usual todepend upon the pieces of wood jamming in the conical bottom to preventtheir falling through the kiln when the slidingdoor is open or partiallyopen.

New, according to my invention ll make use of a kiln which is composedof a body having a conical bottom as above described, the said bottombeing furnished ,With'a discharge opening which is designed to be closedby a hinged drop-down door, which said door merely serves the pi. "poseof controlling the discharge of the charcoal. Above the door the conicalbottom is provided with a grate upon which the wood or other materialrests and having sliding bars, or any other suitable devices, so as tocontrol the flow therethrough of air which enters laterally the spacebetween the said bars and the aforesaid door.

The body of the kiln is preferably made in sections for easy handlingand erection and is furnished with a series of. air inlet holes whichmay advantageously serve as inspection holes as above described, andthese holes may be fitted with means, such as doors, whereby they may beopened or closed as desired. These holes may open directly into theinterior of thekiln, or they may open into annular ringsthemselves incommunication with the interior ofthe kiln. or, the introduction of airto the body of the kiln maybe controlled in any other desired manner.

To enable my invention to be fully under- Specification of LettersPatent.

howing the discharge outlet opened. Fig. 0 is a view similar to Fig. 3illustrating a modification, and 6 is a sectional plan thereof. Figs. 7and 8 are a front view and a vertical section, respectively, drawnectional view of the lower part thereof to a larger scale illustratingone of the draught regulating doors, and Figs. 9 and 10 are two viewssimilar to Figs. 7 and. 8 of a modification hereinafter described 66represents the body'of the kiln, which preferably made in sections asappears rom Figs. 1, and 5, the object of this construction being tofacilitate the transport, erection and handling of the apparatus, thesaid sections being advantageously connected together in the mannerhereinafter described.

72 is the conical bottom of the body a and c is the discharge openingwhich is provided at the lower ape end of the said conical portion 5.

cl is the door for controlling the discharge of the charcoal, the saiddoor being of the drop down type and being hinged at e to a frame 7provided externally upon the bottom of the body a of the kiln below thedlscharge opening 0.

g are the fire-bars which form a grate upon which the Wood or othermaterial rests, the said bars being located above the door (Z and beingarranged so that they can slide in holes 7a in the aforesaid frame uponwhich the door cl is hinged. The holes it constitute inlets for airwhich thus enters laterally into the space 71. between the dischargeopening a and the door (Z when the latter is closed.

i are the inlet holes which are formed in the body a of the kiln and, inthe construc .trated in Figs. 9 and 10, such arrangement comprising ahorizontally sliding door a whichmoves in guides in a frameo attached tothe'outside of the kiln body adjacent to the opening z', similarly tothe frames Z.

The air inlet, whatever be the nature of the door or the equivalent bymeans of which the passage of air therethrough may be regulated, mayopen directly into the interior of the kiln body, as shown in theconstruction illustrated'in Figs. '1 to 4,01 they may open into annularpassages ,7) as in the construction shown in Figs. 5 and 6. Theseannular passages 29 are formed in the body of the kiln and open atintervals, as shown at Q into the interior of the kiln. I v

The kiln is utilized as follows, that is to say, the body has stackedWithin it the wood to be converted to charcoal, and the door (Z isopened and the lire-bars g placedin the position shown in F 3. the woodi then ignited through the open bottom and when the combustion hasstarted the door d is closed and all or any of the fire-bars can bedrawnxont'or partially drawn out, as re quired, for properly regulatingthe admis sion of air through theholes 7t mtothe botraces i5 tom of thekiln body independently of the door (Z; also, as will be understood, theair inlets i to the body of the kiln are opened to an extent necessaryto eifect' the proper control of the charooaling operation.

Claims.

1. A charcoal kiln comprising a body,,and a conical bottom provided withadischarge opening, a door controlling the said discharge opening, a.grate located above the door and beneath the discharge opening and meansfor regulating the inlet of air inclependently of the door.

9,. A charcoal kiln comprising a'body, and a conical bottom providedwith a discharge opening, a door controlling the said discharge pening,a, grate located above the door and beneath the discharge opening andmeans for re ulating the inlet of air through the grate independently ofthe door. 3. A charcoal kiln comprising a body, a conical bottom to thesaid body provided with a'discharge opening, the said bottom having agrate located beneath said discharge opening, a discharge door located"below the grate and means whereby the ad- .mission'of air through thegrate can be regulated independently of the door.

i. In charcoal kilns of 'tliekmd descrlbed,

the combination with the kiln body, of a conical bottom therefor, agrate having a 79 plurality of fire bars slidable in holes in a framebelow the said grate, and a drop-down. door hinged to said frame belowsaid holes.
